v l.lipplication filed December 8, 1905. Serial No. 290.982.

To all 'lull/0m, 'U 'nt/ty concern.

Be itknown that we, MARSHAL D. JONES and DAVID PATTERSON, Acitizens of the United States, residingv at Davenport, in the county of Scottv and State of'Iowa, have 'invented a new and useful Grease-Cup, of which the -following is a specification. l

This invention `relates to lubricators, and more particularly to an improved' o1 l '.or

grease'cup for automatically feeding lubri? cantv to the moving parts of machineryI and the like.

The object ofthe invention is to provide al grease-cup consisting of a pair of telescoping members, one of which is adapted to contain s the lubricantA and'is provided with laterallylextending lugs for engagement with corresponding'notches in the walls vof the adjacent member, whereby the tension of the feed vspring may be adjusted to regulate the pres# sure exertedl by the plunger -iny 'feeding the lubricant to the discharge-passage- A further object of the invention is to provide a series of removable 'disks or diaphragms having diHerent-sized feed-openings formed' therein'for regulating'the quantity of lubri cant delivered to the discharge-passage.

With these and other .objects in view the invention consists in the constructiortand lnovel combination and arran ement o f parts.

hereinafter fully described, il ustrated in the accompanying-drawings, and pointed out inv the claims hereto appended.

' while t e memberv 6 forms a cap or closure' lIn the accompanying drawings, forinin a part of this s ecification, Figure' 1 is a side e evation, part y in perspective, of a lubricatorv or grease-cup constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail perspective view of one of the perforated disks'or. diaphragme detached, and Fig.v 4 is a similar view of another perforated .disk having a larger feed-o ening formed therein.

Similar numera s of reference'indicate corresponding parts in .all the figures of the member 5 bein adapted to contain a 'quanf tity of ease, oi ,or other Suitable material .7,

for the lubricant-containing member and is provided in the top thereof with an opening 8 for the reception of the ro'd9 of a plunger 10.

The member is formed with a dependin enlargement 11, provided with termin Y ASpecification o f Letters Patent.

Patented Nov. 6, 19,06.

extending longitudinally of said enlargement and communicating with the interior of the member 5 is an opening or passage 13,-through which the lubricant is fed to lubrication.

The plunger 10 is rovided` with a vertical iiange or collar 14, w ich forms a Seat for one end ofa conical-shaped coiled spring 15,*the opposite. end of which bears against a flange 16, depending from the top of the member-6, as shown.

Secured to or formed integral with the side walls of the member 5 are laterallyeextending lugs 17 ,adaptedto engage vnotches or re- .cesses 18, formed'in the sidewalls o f the member 6, and communicating with a verticallydisposed slot. 19, so that by' rotating the 19 and then adjusting said member vertically and moving any two of the notches into enspring may be 'adjusted to insure a unicause. the latter. to bepositively fed tothe machinev l ttention is here called to the fact that the 8s the slot 19 are inclined or curved, as indiwalls of the locking notches or recesses 18 at cated at 20, whereb the lugs will be guidedsion of the coiled spring.

As a means for regulating the amount of l'ubricant fed to the' discharge-passage 13 there is provided one or vmore disks or'diaphragms21, which rest upon the bottom Wall posedin alinement with thepas'sagel and passage.

The plunger-rod 9 is preferably provided with a threaded knob or handle 23, so that the same may be uickly removed when it is desired to detach t e several parts.

In operation one of the disks or diaphragms 21 is first placed within the feed cup or member 5,'after which the latter is filled or partially filled with rease, oil, or other lubricant, and the mem er 6, carrying the plunger, placed on. the member 5, and .the

6 until the lugs engage the adjacent lockingnotches in the manner before described.

When it is desired to feed alarger or smaller moving parts of a machine or the like, and 1 of the member 5 and are provided with differ# entsiz'ed feed-apertures 22.', preferably disparts requiring member 6 until the lugsregister with the slot I gagement with the lu'gs the tension of the form pressure on the lubricant, and 'thus' into said notches an held therein by the tenl through which the lubricant is fed to said `two locked together by rotating the member y quantity of lubricant to the discharge-pas- A shape, as shown, it. aiiords a larger bearingsurface for contact with the plunger and insures a uniform pressure thereon, while the iianges on the plunger and member 6 serve to center the spring and prevent accidental displacement ofthe same. .A

Having thus described the invention,what is claimed is 1. Adcvice ofthe classdescribed comprising a pair of telescopic members one of which is provided with a discharge-opening and adapted to contain a lubricant and the opposite member formed with vertically-disposed slots the oppositewalls of which are provided with, locking-notches disposedin staggered relation to each other, a plunger for feeding v'the lubricant to the discharge-opening, a

spring' bearing against the plunger, .and a removable disk disposed above the dischargeopening and provided .with a feed-aperture,

I' I there being oppositely-disposed lugscarried by the lubricant-containing member and adapted to alternately engage the lockingnotches in the walls of the vertical slots.

2. A device of the class described comprisingapair of telescopic members one of which is provided with a discharge-opening and adapted to contain a' lubricant and the adjacent member formed with vertically-disposed slots the opposite walls of Which are curved laterally to produce locking-notches disposed in staggered relation and communicating with said slots, a plunger for feeding the lubricant to the discharge-opening, and a vengage the locking-notches in the walls of the vertical slots.

3. A device of the class described comprising a pair of telescopic members one of which is provided with a discharge-opening and adapted to contain a lubricant and the adjacent member provided with a perforated cap and having vertically-disposed slots formed therein, the walls of which are provided with locking-notches disposed in staggered relation and. communicating with the slots, a plunger for feeding the lubricant to the discharge-opening, a rod carried by the plunger and extending through the perforation in the cap, a spring interposed between the plunger and cap, and a removable disk disposed above the discharge-o ening and rovided with a feed-aperture isposed in a inenient with the discharge-opening,V there being lugs secured to the"lubricant-containing member and adapted to alternately engage the lockin -notches in the walls 'of the vertical slots.

n testimony that We claim the foregoing .as our own we have hereto a'liixed our signatures in thev presence of two witnesses.
